We can say that the journey of EURO PRESS PACK began in 1919, with the creation of the RAFFAELE RIMASSA COMPANY who traded high-pressure hydraulic products in all Europe. The company was taken over by EURO PRESS PACK in 1993 and the group is currently a worldwide leader in the manufacturing of high-pressure hydraulic components from 700 to 4000 bars, and has renewed its trademark RARIPRESS as a result of a complete re design of its product range.
Our effort in following the most advanced technology innovations in terms of quality, safety, and reliability are certified since 1996, year in which we were awarded the ISO
9001 Quality System Certification, and more recently in 2008 with the ISO 14001 Quality System Certification.
EURO PRESS PACK products are the only ones in the sector treated with the Nitreg® ONC® process which, for many years now, has been carried out exclusively within our plants.
This process is a thermo-chemical treatment applied to steel, that starts with the liquid nitriding phase followed by an oxidation phase, causing a change in the steel’s superficial chemical structure. This alteration makes steel exceptionally hard and resistant to corrosion. The already enhanced resistance is further strengthened with the application of a special oil that coats the treated surfaces and makes them immune to corrosion (tests conducted in saline smoked rooms show up to 300 hours of resistance to corrosion according to ASTM B117).
Our products, treated with this process, are therefore especially suitable for applications with high risks of corrosion and mechanical wear.
The black colour of all EUROPRESS products is a direct result of the last phase of this unique treatment and has come to symbolize our long lasting effort towards the pursuit of quality.

The ideal choice of materials combined with surfaces treated and protected against corrosion makes EPP products suitable for use in harsh environments.
Furthermore, EUROPRESS cylinders can withstand off-centred and side load forces up to 8% of their nominal capacity. Most of our models are in compliance with ANSI (American National Standard Institute) B30.1 Standard.
Cylinder bodyThe cylinder body, piston and end of stroke nut are in high quality tempered steel and have been treated with a special nitriding process so that these parts have a high wear resistance and are corrosion protected; they have a long outdoor service life even in sea-water and aggressive atmospheres.
WiperThe wiper prevents contamination and thus increases the service life of the cylinder.
Return springThis spring ensures fast piston retraction irrespective of the cylinder position.
SealThe compact seal provides good resistance to wear and extrusion.
SaddleThe saddle is in high tensile and nitrided steel and thus prevents deformation of the piston rod.
Quick couplerThe quick coupler mounted on all cylinders (except COD cylinders), is fitted with a dust cap.

HYDRAULIC CYLINDERSHOW TO CHOOSE A CYLINDER
Some essential information is necessary to choose the correct cylinder. This information includes:
There are three main types of cylinders: , spring return and
oil return.
And some supplementary data such as:
CMF20N100Cylinder, spring return with 20 t. force, N version, 100 mm stroke.
CGG200N250FTLoad return cylinder with safety nut, 200 t. force, N version, 250 mm stroke with fixing holes in the base and integral saddle.
Example: cylinder

In the Useful pages you may find some calculation examples.
Spring return Spring assisted return , in which the piston is retracted by means of an internal compression or tension spring inside the cylinder .These cylinders are proposed whenever it is necessary to remove the cylinder quickly once the load has been lowered.
The cylinders of the CMC, CMF, CMI, CML, CMP,
CMT ranges belong to this group.
Oil returnOil Return, (double acting): the piston is retracted hydraulically by pumping oil into the anular chamber of the cylinder.These cylinders are ideal for use in production applications where a fast cycle time is required. When being used in a lifting application, lowering of the load can be controlled by fitting a pilot check valve and one-way flow distributor into the circuit.The return pressure can be set at a lower value when it is only
needed to retract the piston. The cylinders of the COF, COI, COS ranges belong to this group.When it is necessary also to exert a pulling force, we recommend cylinders belonging to the COD ranges . These cylinders are supplied complete with the required threads and connections and may also be operated at the maximum working pressure on both sides of the piston.
Load return
Load return , in which the piston is retracted by the weight of the load (or any other external force). The minimum force required to retract the piston is approximately 0,2% of the rated cylinder nominal push value. These cylinders are the most economic solution for an application that does not
require quick removal of the cylinder after the load has been lowered. The cylinders of the CGG, CGR, CGS ranges belong to this group.
Construction of the “Second Bridge over the Panama Canal - Republic of Panama” for which EUROPRESS has supplied the hydraulic components that hold the segments for the construction of the floor system of the bridge (Panama, July 2003)
Construction of “Sistema de Transporte de la Región Central de Venezuela, Primera Etapa Caracas Tuy-Medio” through the development of railway viaducts with metallic floor systems lowered with EUROPRESS hydraulic equipment (Caracas,Venezuela June 2003)

These cylinders are particularly suitable for applications in which the load has to be supported for long periods.The lock nut can be screwed down onto the cylinder body to hold the load mechanically. This ensures that operation
under load is absolutely safe.
CGG cylinders have concentric grooves machined into the end of the rod to improve load grip, models above 30 tonne have lifting eyelets for ease of transport. From 50 tonnes upwards, the cylinders are plunging type and have device which prevents any over-stroke. The rod has a coloured zone which becomes visible 10 mm before the end of the piston stroke.
All models can operate with off-centred load up to 8% of their nominal capacity.
OPERATIONAL AREAS
These cylinders are ideal for use in the Construction Industry, e.g. Bridge repair and construction, foundations and underpinning etc.
The anti-corrosion treatment applied to these cylinders
during manufacture makes them suitable for use in harsh
and aggressive environments.

Pancake lock ring cylinders have an overflow port to limit stroke. The rod on these cylinders has a coloured area which appears 10mm before the maximum stroke has been reached. This version does not conform to ANSI B30.1.
These cylinders are particularly suited to applications where the load has to be left in a raised position for long periods. The load can be supported by the safety lock nut, this allows the pressure to be released and the pumps and hoses can be disconnected until it is necessary to lower the load.
All cylinders are supplied with integrated tilt saddle and eyelets for ease of transport.
OPERATIONAL AREAS
CGR cylinders are ideal for use in the construction and maintenance of bridges, viaducts, building sites and industrial maintenance where working space is limited.
The protective nitriding treatment on these cylinders gives
excellent resistance to corrosion making them suitable for
use in aggressive environments.
LOW PROFILE CYLINDERS WITH SAFETY RING NUT, LOAD RETURN
Integrated tilt saddle, reducing the effects of possible off-centred loads.
STANDARD
CGR cylinders have been designed for use in applications where space is limited and to stand the full load even without a pressure distribution plate below. It is anyhow recommended that pressure plates are placed both under the base and on top of the saddle to distribute the load if the support resistance is not compatible with the pressure shown in the chart.
Non compliance with this notice could result in damage to the cylinder and/or the load being lifted.
During the lifting operation the operator must always be in a position to observe when the coloured end of stroke section of the rod appears.

Some essential information is necessary to choose the correct pump. This information is:• Reservoir capacity
• Cylinder plunger speed
PUMP SELECTION BASED ON ITS TANK CAPACITY
After having selected the most suitable cylinder and determined the oil volume required for the stroke, it is now necessary to choose the most suitable pump based upon the required oil volume. This volume can be defined by 1.1 multiplication of the oil
volume required for the selected cylinder(s). In the case of double acting cylinders the retraction oil volume shall be subtracted from the volume of oil required to extend the cylinder. Finally, the quantity of oil needed to fill the flexible hoses, i.e. 32 cm3 per meter length, needs to be taken into account. The following tables will permit an easy choice.
The coloured zones represent the maximum utilisation limits for each pump type.

Synchrolift (Synchronous Lifting System) is the most sophisticated method to lift up and lower down any kind of load in a perfectly synchronised way and with the highest degree of precision.
This system splits the oil flow coming out from a hydraulic power pack and directs it towards different lifting points; it controls and monitors the different flows thanks to a range of electric valves controlled by a PLC.
The PLC controls the flow in the direction of a number of cylinders, checking the signals issued by dynamic transducers and activating appropriately the monitoring valves.
This electric system enables the regulation of the movement of the cylinders stopping and/or slowing down those that exceed the difference in allowed movement as chosen by the client. A PC provides for its control system.
Synchrolift is easy to control, multipurpose and extremely accurate, it can handle simultaneously many lifting points, even with different capacity cylinders.
The programme can also deal both with linear and planar non-parallel lifting operations, counteracting with pinpoint precision structural failure (e.g. a bridge pier, one end of which has yielded).
APPLICATIONS
Our Synchrolift system is necessary every time hydraulic cylinders with different loads are required to lift up and lower down at the same rate (e.g. lifting a 3000 t bridge with 1 mm precision, or squaring a building damaged by seismic activity are only two of the many applications of a synchronised lifting system)
Our Technical Department is at your disposal to study the best technical and operational solution, and deliver tailored solutions on demand.

The Split Flow hydraulic power packs have two or four independent outlets delivering a constant amount of oil, even if the pressure in each line is not the same. They are equipped with:• 3-phase electric motor• pump and tank to be matched with• 2 or 4 (one for each port) 4-way, 3-position manual control valves
with piloted check and 150 bar pressure setting on return B port• 2 or 4 flow control valves (one for each port) for controlled
load lowering• 2 or 4 pressure gauges (one for each port)
APPLICATIONSThey are an efficient and economic solution particularly suitable for lifting up to a maximum of 4 cylinders with different loads. Since they are based on equal geometrical pressure lines, without any external control on the actual stroke, Split Flow power packs provide for ±3% synchronous lifting with visual control of the operation.Furthermore, they also allow for synchronous load lowering operations under load when using double acting cylinders.

SELECTION CHART FOR 1800 - 2500 BAR HOSES
The maximum operating pressure of the pump-hose-coupling system is the working pressure of the lowest rated part.
- Bolt tensioners hoses: SN#FT (with K13X coupler). - Torque wrenches hoses : SQ##FM (male coupler on one side and
female on the other).
The oil volume required to fill the hoses needs to be taken into account when selecting the pump model.
When using closed centre valves the pump must be switched off when the valve lever is in the central position to prevent overheating of the oil.
FEATURES
These valves provide the means to control cylinders and actuators operating at pressures of 700, 1000, 2000 and 3000 Bar.
Specifications.
• VL Manual and electric control valves to operate single acting (3-way) and double acting (4 way) systems• VR Regulating, shut-off and check valves to isolate and monitor
hydraulic systems
Control voltage for solenoids is 230 VACDifferent voltages are available on request.
For installation of the valves on hand pumps PL, refer to the relevant section.
For installation of the valves in modular units, refer to the relevant section.
Follow our safety instructions see useful pages
HOW TO SELECT A VALVE
Please consider the following information when choosing a valve.• Single acting cylinders: these require a 3-way valve (three
outlets: pressure P, tank T, cylinder A)
• Double acting cylinders: these require a 4-way valve (4 outlets, pressure P, tank T, extension A, return B)
• Positions: these are the valve lever position points: extension and retraction of the cylinder (2 position valve) extension, holding and return (3 position valve)
• Centre: Intermediate position. The centre may be open and in this case the valve connects the pump (P) and users (A,B) to the discharge outlet (T), or closed and then all outlets are closed (if you want to isolate the cylinder but use the pump to feed other users)

UTBOLT TENSIONERS 1000 - 1500 BAR
APPLICATIONS
The big advantage of tensioning is given by the fact that it is possible to charge in advance a tie rod with the required load in an extremely precise manner, thus avoiding the force losses due to the frictions of the traditional torque tightening. Their great facility in use, the possibility to save time and staff and their precision are all factors that make this technique particularly useful in those sectors where a perfect coupling or flange tightness is essential for the safety of people and machinery.In particular in the industrial and oil sectors and in all situations where it is necessary to tighten with extremeaccuracy nuts or threaded tie rods. They are widely used to tighten valves, pumps, heat exchangers, flanges, etc.
If you use a tensioning system where you choose to tension in various steps (50%, 33% or even 25% of the points) for space reasons, take care to alternate the tensioners and to locate them in opposite positions.
FEATURES
EUROPRESS bolt tensioners are made of an hydraulic part with a supporting base (bridge) to which a threaded puller and a polygonal wrench in its various sizes may be added. This allows to cover a large number of tie rods and to optimize the number of bolt tensioners necessary. According to their technical characteristics, they differ as:
UTN series at 1000 bar, provide a traction force of about the 70% of the break point of a steel bolt grade 8.8 of the biggest size (value of max thread in the chart).They are equipped with K13M coupler.
UTH series at 1000 bar, with most of these you can obtain a traction force equal to 70% of the yield stress of a steel bolt grade 10.9 of the maximum size (value of max thread in the chart).They are equipped with K13M coupler.
UTV series at 1500 bar, that can develop a traction force of about the 70% of the break point of a steel bolt grade 10.9 of the biggest size (value of max thread in the chart).They have reduced overall dimensions if referred to the 1000 bar series, due to their high working pressure. They are equipped with a K15M coupler, and have a second auxiliary hole (1/4” BSP) that can be joined with a quick coupler (to be ordered separately) for in line connections.
All tensioners are supplied with tommy bar to operate the threaded puller and the polygonal wrench.
The gas nitriding treatment (Nitreg) provided to all steel of EUROPRESS products makes them particularly fit forworking outside or in aggressive locations, thanks to their high resistance to corrosion.
The tensioner maximum capacity refers to its maximum working pressure; for smaller loads reduce the pressure in a proportional way.
To operate in complete safety be careful that the threaded screw sticks out of the nut at least as much as the measure of the diameter of the tensioner.
Tensioning system for roof’s supporting structure while building the new Rome’s Music Auditorium. On this job were used bolt tensioner cylinders specially manufactured from Euro Press Pack. (Rome Italy, 2001)
* This means the minimum centre distance allowing for the installation of one single tensioner without any interference problems. If using a multiple tensioning system, this distance is equal to the figure in column ØD (external diameter)

HOW TO CHOOSE A SYSTEM
The best system can be chosen according to the oil quantity of the bolt tensioner or set of bolt tensioners and the drive speed required. Various types of EUROPRESS pumps can be chosen and combined according to the desired working pressure, their reservoir, capacity and the valve function. A gauge with eventually its gauge adaptor and a hose complete with coupler (with the correct working pressure according to the chosen bolt tensioner), must always be combined with the pump.
FEATURES
Made of steel and equipped with a hydraulic part, they are produced on request and can be customised according to specific needs. The hydraulic part is made of standard products with single or double acting cylinder, single or double phase pump and gauge to guarantee more safety to the system.

The calculation examples given serve as a basis for the useof hydraulic systems.
1. FORCE OF AN HYDRAULIC CYLINDER
The force of an hydraulic cylinder results from the pressurein the cylinder, p, on the piston of the cylinder
The formula: F(kg) = p(bar). A(cm2) [being = 10N .m ]means:F = force acting on the cylinder in kgp = operating pressure in barA = the cylinder effective area in cm2 which is calculated from the piston diameter:
A(cm2) = d(mm)2. π (π = 3,1416)
EXAMPLE 1:A CGG100P50 cylinder is required to lift a load of 72 t.What operating pressure is required?
A(cm2) = d(mm)2. π
with piston diameter CGS100P50
d = 130 mm
A = 1302.3,1416 cm2 = 132,7 cm2
the result of F(kg) = p(bar). A(cm2 ) after its inversion, is
p(bar) = F(Kg) being F = 72 t = 72.000 kg
p = 72.000 bar = 542 bar.
The required operating system is 542 bar.
EXAMPLE 2:
A CMI10N100 cylinder lifts a load; the gauge shows an operating pressure of 520 bar. What is the weight of the load?
A(cm2 ) = d(mm)2. π
With piston diameter CMI10N100 d = 45 mm
A = 452.3,1416 cm2 = 15,9 cm2
F(kg) = p(bar). A(cm2) F = (520 . 15,9) kg = 8270 kg
The lifted load has a weight of 8270 kg.
2. ACTUATING PUMPS
When an hydraulic cylinder is operated by a hand pump, the cylinder plunger moves a certain distance per pump actuation. This distance depends on the cylinders effective area and on the pump’s oil flow per stroke. When two-speed hand pumps are used, the low pressure oil flow VLP applies for cylinder movements without load and the high pressure oil flow VHP applies for cylinder movements with loads.
+
(
,
�
The formula: S(mm) = V(cm3).10
means:S = cylinder’s shift in mmV = pump’s oil flow per stroke in cm3A = cylinder area in cm2.
EXAMPLE 3:A CMI10N100 cylinder is operated by a PL131 hand pump. What is the distance the supported load moves per pump actuating?

S(mm) = V(cm3).10
PL131 having an oil flow per stroke of V =3,4 cm3
S = 3,5.10 mm = 2,2 mm
The supported load moves 2,2 mm per pump full stroke actuation.
EXAMPLE 4:A CGG100P50 (stroke S = 50mm) is operated by a PL162 hand pump. A non-load stroke of L = 30 mm has to be accounted for. How many pump actuations PB are necessary to extend the cylinder completely?
A = 132,7 cm2 (See example 1)
Meaning for the non-load stroke SBP (mm) = VBP (cm3).10
PL162 having a LP-oil flow per stroke ofVBP = 32cm3
SBP = 32.10 mm = 2,4 mm
The number of pump actuations in the non –load mode is calculated by way of non-load stroke divided by the movement covered per pump actuation:
PBBP = L(mm) = 30 = 13 pump actuations
Meaning for stroke under load: SAP
(mm) = VAP (cm3).10
PL162 having a LP-oil flow per stroke of
VAP = 3 cm3
SAP
= 3.10 mm = 0,23 mm
The number of pump actuations under load is calculated from the remaining stroke divided by the distance covered per pump actuation:
PBAP
= H(mm) - L(mm) = 50-30 = 87 pump actuations
In total = PBBP + PBAP = 13 + 87 = 100 pump actuations.
3. SPEED OF EXTENDING
The time an hydraulic cylinder needs for extending, being operated by an electric pump, depends on the cylinder effective area and on the oil flow of the electric pump. When two-speed pumps are used, the LP-oil volume QLP for cylinder movements without load and the HP-oil volume QHP for cylinder movements with load is to be put in.

The Formula: v(mm/s) = Q(l/min).166,67
means:v = speed of the cylinder in mm/sQ = the oil flow of the pump in l/minA = cylinder area in cm2
EXAMPLE 5:A CGG100P50 is operated by an electric pump MEF10M31. What is the cylinder’s speed of full extension?
A = 132,7 cm2 (see example 1)
v(mm/s) = Q(l/min).166,67
having an oil flow MEF10M31 | Q = 1,8 l/min
v = 1,8.166,67 mm/s = 2,2 mm/s.
The cylinder’s speed of full extension is 2,2 mm/s.

Always provide a solid support for the entire cylinder base area.
Never place any part of your body under the load and for additional safety support the load mechanically.
EPP components have been treated against corrosion. Nevertheless in case of operations in very humid areas or marine environments, please contact our Technical Department for more information.
Keep your hydraulic equipment away from temperatures above 65°C (150°F).
Make sure that the two areas on which the cylinder develop its force are sufficiently strong and non-deformable.
The cylinder saddle must be in contact with the load and the cylinder movement must be in axis with the load movement.
To hold the load lifted use a needle or a pilot check valve in addition to the pump or power pack valve. In case the load has to be held over a long period use a cylinder with a safety lock nut.
Never use cylinders without the saddle, as they distribute the load evenly and prevent damage to the piston.
Avoid any lifting of off centred loads which could damage the cylinder. The use of a tilt saddle allows a misalignment of the load ± 5°.
Never work near the load supported only by the hydraulics. The safety lock nut of the cylinders has to be continuously screwed down onto the body of the cylinder during the lifting operation.

USEFUL PAGESSAFETY INSTRUCTIONS
Avoid retracting the piston too quickly if it is still under load. A sudden retraction creates pressure shocks in the hydraulic circuit. Slowly turn the hand pump and power pack release valve. When 4/3 valves are used in a maintained position it is advised to insert a needle valve between the directional valve and the cylinder in order to have a controlled lowering speed of the load.
Always keep the hoses away from the area under the load.
Do not use any component with a load exceeding their nominal capacity. Always use a gauge to check the circuit pressure or tonnage.
Never exceed the maximum working pressure indicated for any cylinder range.
Before connecting, clean the couplers properly and to avoid contamination use the dust caps when not connected.
Do not lift any hydraulic component by the hose
Only disconnect the cylinder from the pump when the rod has fully retracted.
HYDRAULIC HOSES
EUROPRESS CYLINDERS HAVE BEEN DESIGNED WITH GREAT SAFETY MARGINS. NEVERTHELESS TO AVOID TO UNDERVALUATE THE LOAD TO BE LIFTED, ALWAYS CHOOSE A CYLINDER WITH AT LEAST 20% MORE CAPACITY THAN THE REQUESTED LOAD.
Do not kink hoses. The bending radius must not be under 70 mm. Do not walk over or drop heavy objects on them.
This catalogue has been prepared with as much care as possible. All data and information have been checked and verified before printing. In spite of this and due to the continuous improvement and evolution of the EUROPRESS production range, we take the right to modify or abolish any products from this catalogue.

Integral or partial use and reproduction of this catalogue is prohibited (drawings, pictures, texts, photographs, logos) unless written authorised.
Use EUROPRESS hydraulic oil only, to keep the seals intact.
We recommend to use EUROPRESS hydraulic oil only. Its viscosity and lubrification features guarantee the highest operational efficiency and a longer life of the equipment. The hydraulic oil temperature must not exceed 60°C (140° F). To operate at higher temperatures or with different fluids please contact our Technical Department.
We recommend to read carefully EUROPRESS safety instructions before use.
Never refill the pump above indicated level and whilst the pump is connected to a partially extended cylinder.
Do not use any extension on the pump handle. Operate hand pumps is easy, when properly handled.
Use your fingers to close the release valve, a tool could cause damage.
